The London Fire and Emergency Planning Authority (LFEPA), the body which governs the fire service, has recorded its opposition to the station closures.
It is likely that the vice-chair Richard Tracey, who retained his Assembly seat for Merton and Wandsworth, will take over until LFEPA holds its annual meeting in June.
Green Party Assembly Member Darren Johnson, a member of the London Fire and Emergency Planning Authority (LFEPA) which governs the fire service, was among those who requested the figures.
Mr Coleman has also lost his position as chair of the London Fire and Emergency Planning Authority (LFEPA), a role that came with his status as an Assembly member.
The mayor can handpick two appointees to LFEPA and a City Hall source said "everything is still up for grabs" with a raft of appointments to be made in the coming days.
